In our examination, we have assumed the genuineness of all signatures, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as facsimile, electronic, certified or photostatic copies, and the authenticity of the originals of such copies. As to any facts relevant to the opinions stated herein that we did not independently establish or verify, we have relied upon statements and representations of officers and other representatives of the Transaction Parties and others and of public officials, including those in the Secretary’s Certificate and the Director’s Certificate and the factual representations and warranties contained in the Underwriting Agreement.

We do not express any opinion with respect to the laws of any jurisdiction other than (i) the laws of the State of New York and (ii) the Delaware Revised Uniform Limited Partnership Act (“DRULPA”) (all of the foregoing being referred to as “Opined on Law”).

As used herein, “Transaction Agreements” means the Underwriting Agreement, the Indenture and the Note Certificate.

Based upon the foregoing and subject to the qualifications and assumptions stated herein, we are of the opinion that:

1.                                      The Note Certificate has been duly authorized by all requisite limited partnership action on the part of SL Green OP and duly executed by SL Green OP under DRULPA, and when duly authenticated by the Trustee and issued and delivered by SL Green OP against payment therefor in accordance with the terms of the Underwriting Agreement and the Indenture, the Note Certificate will constitute the valid and binding obligation of SL Green OP, entitled to the benefits of the Indenture and enforceable against SL Green OP in accordance with its terms under the laws of the State of New York.

2.                                      The Guarantee of Reckson has been duly authorized by all requisite limited partnership action on the part of Reckson under DRULPA and duly executed by Reckson under DRUPLA and, when the Note Certificate is issued and delivered by SL Green OP against payment therefor in accordance with the terms of the Underwriting Agreement and the Indenture, the Guarantee of Reckson will constitute the valid and binding obligation of Reckson, enforceable against Reckson in accordance with its terms under the laws of the State of New York.

3.                                      When the Note Certificate is issued and delivered by SL Green OP against payment therefor in accordance with the terms of the Underwriting Agreement and the Indenture, the Guarantee of the Company will constitute the valid and binding obligation of the Company, enforceable against the Company in accordance with its terms under the laws of the State of New York.

The opinions stated herein are subject to the following qualifications:

(a)                                 the opinions stated herein are limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer, preference and other similar laws affecting creditors’ rights generally, and by general principles of equity (regardless of whether enforcement is sought in equity or at law);

(b)                                 we do not express any opinion with respect to any law, rule or regulation that is applicable to any party to any of the Transaction Agreements or the transactions contemplated thereby solely because such law, rule or regulation is part of a

5

regulatory regime applicable to any such party or any of its affiliates as a result of the specific assets or business operations of such party or such affiliates;

(c)                                  except to the extent expressly stated in the opinions contained herein, we have assumed that each of the Transaction Agreements constitutes the valid and binding obligation of each party to such Transaction Agreement, enforceable against such party in accordance with its terms;

(d)                                 we do not express any opinion with respect to the enforceability of any provision contained in any Transaction Agreement relating to any indemnification, contribution, exculpation, release or waiver that may be contrary to public policy or violative of federal or state securities laws, rules or regulations;

(e)                                  we call to your attention that irrespective of the agreement of the parties to any Transaction Agreement, a court may decline to hear a case on grounds of forum non conveniens or other doctrine limiting the availability of such court as a forum for resolution of disputes; in addition, we call to your attention that we do not express any opinion with respect to the subject matter jurisdiction of the federal courts of the United States of America in any action arising out of or relating to any Transaction Agreement;

(f)                                   we do not express any opinion with respect to the enforceability of Section 8.1 of the Indenture to the extent that such section provides that the obligations of the Guarantors are absolute and unconditional irrespective of the enforceability or genuineness of the Indenture or the effect thereof on the opinions herein stated;

(g)                                  we do not express any opinion with respect to the enforceability of the provisions contained in Section 8.2 of the Indenture to the extent that such provisions limit the obligation of the Guarantors under the Indenture or any right of contribution of any party with respect to the Guarantees;

(h)                                 we have assumed that the Operating Partnership Agreement is the only partnership agreement, as defined under DRUPLA, of SL Green OP;

(i)                                     we have assumed that the Reckson LP Agreement is the only partnership agreement, as defined under DRUPLA, of Reckson;

(j)                                    we have assumed that each of SL Green OP and Reckson has, and since the time of its formation has had, at least one validly admitted and existing limited partner and (i) no procedures have been instituted for, and no other event has occurred, including, without limitation, any action taken by SL Green OP, Reckson or any of their respective general partners or partners, that would result in the liquidation, dissolution or winding-up of SL Green OP or Reckson, (ii) no event has occurred that has adversely affected the good standing of either SL Green OP or Reckson under the laws of its jurisdiction of formation, and each of SL Green OP and Reckson  has taken all actions

6

required by the laws of its jurisdiction of formation to maintain such good standing and (iii) no grounds exist for the revocation or forfeiture of either SL Green OP or Reckson’s Certificate of Limited Partnership; and

(k)                                 to the extent that any opinion relates to the enforceability of the choice of New York law and choice of New York forum provisions contained in any Transaction Agreement, the opinions stated herein are subject to the qualification that such enforceability may be subject to, in each case, (i) the exceptions and limitations in sections 5-1401 and 5-1402 and (ii) principles of comity and constitutionality.

In addition, in rendering the foregoing opinions we have assumed that, at all applicable times:
